Cryptography tutorial pdf
WebPublic Key Cryptography Each user has an encryption function and a decryption function. • Alice makes her encryption function E A publicly known, but keeps her decryption function D A secret. • Bob wants to send Alice a message P, so he computes C = E A(P) and sends it to her. • Alice receives C and computes P = D A(C). WebThis tutorial covers the basics of the science of cryptography. It explains how programmers and network professionals can use cryptography to maintain the privacy of computer data. Starting with the origins of cryptography, it moves on to explain cryptosystems, various traditional and modern ciphers, public key
